Negative bias temperature instability (NBTI) has become a critical reliability phenomena in advanced CMOS technology. In this paper, we propose an analytical temperature-aware dynamic NBTI model, which can be used in two circuit operation cases: executing tasks with different temperatures, and switching between active and standby mode. A PMOS Vth degradation model and a digital circuits’ tempor...

Standby power is electric power that a device consumes when not in present use, but plugged in to a source of power and ready to be used. Present estimates indicate that standby power consumption reaches 10 to 15 percent of total residential electrical use. In this paper, we propose a Host-Agent based standby power control mechanism in home network environment. It uses the IEEE 802.15.4 based Z...

Abstract: This paper proposes a new scheme to improve the standby efficiency of the high-power half-bridge line level control (LLC) resonant converter. This new circuit is applicable to improving the efficiency of the renewable energy generation system in distributed power systems. The main purpose is to achieve high-efficiency solar and wind power and stable output under different load conditi...

BACKGROUND Implantable heart rhythm devices are susceptible to interference in hospitals where electromagnetic interference (EMI) sources are ubiquitous. CASE DESCRIPTION We report three cases in which EMI from the external defibrillator caused the inability to interrogate Boston Scientific cardiac resynchronization therapy-pacemaker (CRT-P) devices. We have documented interference with the B...

ABSTRACT: SRAM area is expected to exceed 90% of overall chip area because of the demand for higher performance, lower power, and higher integration. To increase memory density, memory bitcells are scaled to reduce their area by 50% each technology node. High density SRAM bitcells use the smallest devices in a technology, making SRAM more vulnerable for variations. This variation effect the sta...

A complex multi-state redundant system with preventive maintenance subject to multiple events is considered. The online unit can undergo several types of failure: both internal and those provoked by external shocks. Multiple degradation levels are assumed as external. Degradation observed random inspections and, if they major, the goes a repair facility where carried out. This composed single r...

A stochastic model for a cold standby system of two identical units is developed in which unit fails completely either directly from normal mode or via partial failure. The unit undergoes preventive maintenance (PM) after a maximum operation time (MOT) at its partial failure stage (PFS). There is a single server who visits the system immediately as and when needed to do preventive maintenance a...

This paper presents a new multi-objective mathematical model for the redundancy allocation problem with the choices of a redundancy strategy and component type in series-parallel systems. The model considers entropy measure which is a measure of uncertainty in the information theory. For the first time, the model maximizes the reliability and entropy of the system and minimizes the nonlinear co...
